LIDAR, LRF, etc HELP!
July 6, 2012
So I love lasers. Really, really love them. I've bought about a dozen different types of laser modules (green/red) to play with on my next bot. However I'm at a loss as to where to even begin on using them as more than just a "frickin laser beam", and have it actually DO SOMETHING!
I've been scouring the net and LMR for info on building a cheap Laser Rangefinder and/or LIDAR system, I love the idea of mapping a room with lasers and having the information sent back to the microprocessor and/or base station pc for visual processing by the user. However, I'm also confused about these two terms; are they the same thing?
I've seen Fritzl's post (http://letsmakerobots.com/node/1833) about a DIY LRF using visible LED light and a Photoresistor, is something like this possible with a laser? Wouldn't that just be a simple range finder like the Sharp IR's? I want something more elaborate than that.
Then there's the ol' webcam/laser pointer setup (https://sites.google.com/site/todddanko/home/webcam_laser_ranger) but not really the route I want to go.
Also does anyone have any suggestions for machine vision via Kinect/Webcam/CMUcam etc?
Any help or suggestions would be greatly appreciated!
